Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing further illustrates the present invention.
As shown in drawings, the impact type isotope releaser of the present invention, it is made up of the first half and the latter half, the first half there is rope socket 1 be fixed on above rope socket joint 2, switch control rule cover 3 is connected with below rope socket joint, switch control rule cover outside is set with the first spring 6, alignment pin 5 is had to be fixed on switch control rule cover outside above first spring, switch control rule cover outside has top urceolus 27 and bottom urceolus 7 respectively, and the pressure cap 4 with longitudinal keyway 28 is arranged on urceolus upper end, top, there is lock sleeve 10 on the lower half, there is the cutting seam 9 of multiple tracks longitudinal direction the upper end of lock sleeve, lock sleeve is fixed on the upper end of top connection 11 by screw thread, the lower end of top connection is connected with into water dosing mouth joint 13, water inlet dosing mouth joint there are inlet opening 15 and interior dosing mouth 16, be set with dosing mouth outside the water inlet dosing mouth joint at interior dosing mouth position and close cover 17, dosing mouth is closed and has been put outer medicine feeding hole 18, the double-purpose valve 12 of band intake tunnel 14 is had to be fixed on center driving control link 8 inside position, inlet opening, water inlet dosing mouth joint lower end is connected with isotope storehouse cylinder 19, cylinder bottom, isotope storehouse has multiple isotope release aperture 22, lower contact 23 top and isotope storehouse cylinder link together, lower contact bottom and tester connector 26 link together, the tapered valve 20 of band sealing ring 21 is arranged at center driving control link bottom, center driving control link top is successively through isotope storehouse cylinder, water inlet dosing mouth joint, top connection, center driving control link upper end is positioned at lock sleeve, end, center driving control link upper end is jujube core shape, the position that center driving control link bottom is positioned at tester connector is set with return spring 24, the lower end of the center driving control link below return spring is provided with elastic force adjusting nut 25, the first half and the latter half are linked together by bottom urceolus and top connection, and the upper end of center driving control link is positioned at the centre bore 29 of switch control rule cover lower end.
Before this device uses, first the first spring that switch control rule cover puts together with switch control rule is pulled upwardly, when the positioning key that switch control rule puts is pulled to pressure cap top along keyway, rotate to an angle, alignment pin 5 is stuck on the upper surface of pressure cap nonbonding groove location.The first spring that now switch control rule puts is in compressive state.Due to the stop of positioning key, switch control rule cover can not be descending because of the effect of the first spring.
Then, wedging ring is at the return spring of the center driving control link bottom of lower controller, make the center driving control link upwards action being fixed with double-purpose valve and taper valve, when the head at center driving control link top exposes lock sleeve, revolution switch controls cover, the positioning key of switch control rule cover is descending along the keyway inside pressure cap, and lock sleeve is entered in switch control rule cover.Rotate dosing mouth and close cover 17, outer medicine feeding hole 18 is communicated with interior medicine feeding hole 16, isotope is joined in the cylinder of isotope storehouse by inside and outside medicine feeding hole.Rotate dosing mouth again and close cover, medicine feeding hole 16 in closing, now isotope releaser enters state to be released.
During use, this isotope releaser is connected to logger upper end by tester connector 26, rope socket 1 upper end connect steel wire for logging, under enter by well logging in.When arriving release depth, face winch brake tightly of stopping fast, realizes anxious stopping, and now the switch control rule of the first half overlaps 3, rope socket joint 2 is slack with rope socket 1, and miscellaneous part and instrument together continue descending.When overcoming the elastic force of the first spring, lock sleeve deviates from the centre bore of switch control rule cover 3, and lock sleeve opens immediately, and lock sleeve, under return spring effect, drives center driving control link to move down.Meanwhile, the end, upper end of center driving control link jujube core shape, after the constraint losing lock sleeve, drives double-purpose valve and taper valve synchronously to move down return.Now, double-purpose valve no longer blocks inlet opening, the intake tunnel 14 of injection water in pit shaft on inlet opening, double-purpose valve, by the isotope in the cylinder of isotope storehouse after isotope release aperture is gone out, under the effect of the injection water of isotope in pit shaft, continue descending, after together entering mined bed with injection water, the tester be connected under device can carry out intake profile test.
Top urceolus and bottom urceolus can be integral.
